ARM: uniphier: add sg_set_iectrl_range()
For PH1-LD20 or later, per-pin input-enable control is supported, that is, we need to set-up IECTRL registers for a group of pins. This helper function will be useful for a bunch of register settings. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
